Paterte d Nov., 9, 1920,.

'To all whom it may camera Be it known that I, JAMES E. BUSHNEL'L, a citizen of the United States, residing at Cold Springs, County of Putnam, and State of New York, have invented certain new and useful Tmprovements in Car-Axle Mountings, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to a mounting for car-axle boxes upon the bodies of small cars like mine-cars; and the object of the invention is to furnish a means, without any complicated attachments, of rendering the two boxes upon each axle self-alin ing and to hold them firmly in such alined position, preferably by the same means that secures them to the bottom or frame of the car. Such self-alinement is obtained by providing clearance between the axle-boxes and the parts which hold them upon the car-body. v

Means is provided for securing the boxes firmly at a suitable distance apart to hold the axle from end-play, and to rigidly resist any thrust along the axle.

The thrust in the direction of travel is resisted by simple lugs cast upon the axleboxes, Operating with a channel tie-bar which holds the boxes upon the car-body.

These objects are attained by extending the channel bar across the bottom of the ,car-body with the flanges projected downintegral with the axle-boxes.

This connects' both of the axle-boxes firmly to the same channel-bar, and clearance is provided upon the boxes to permit their self-alinement in every direction, to the small extent that is necessary, while affording a rigidconnection of the parte The invention will be understood by reference to the annexed drawingn which Figure 1 is an elevation of one pair ot wheels with their complete mounting upon a car-bottom; Fig. 2 is a cross-section of the parts shown in Fig. 1 taken on line 2-2 in Fig. 4:; Fig. 3 is a perspective View showing a car-axle with the boxes thereon, and a part of the channel-bar engaged with one of the boxes which is nearly concealed;

Fig. 4: shows the upper side of one of the axle-boxes with the portion oi" the axle which extends through the same, and a horizontal section of the channel-flanges at the ends of the lugs f; and Fig. 5 is a side elevation of the parts in connection with one of the axle-boxes.

Figs. 2 to 5 inclusive are upon a scale three times as great as Fig. 1.

A designates the body of the car, or a bolster extended across the same. A channel bar a, a' is Secured to the bottom of the car by bolts Z. B designates the axle, with wheels C upon its ends. The body D of the axle-boxes is shown fitted with clearance, between the flanges a', which. project downwardly from the web a of the channel-bar.

The channel-bar is extended across the bottom of the car-body immediately above the axle, and its flanges notched at c at the sides of each box. The bolts Z pass through holes Z' in the web, with clearance to permit the required adjustment.

The axle-boxesare cast of a single piece with a wing d upon each side, adapted to fit into and loosely engage the notch a in the channel-fiange, to resist end-thrust. The axle-box has also a lug f projected from each side toward the inner side-of the channel-flange to engage the same loosely, so that t it may resist side-thrust upon the axle.

Bolt-hole g are extended through the channels adjacent to the notches c, and corresponding bolt-holes e are extended Vertically through the wings into recesses h upon the/under sides of the wings. Bolts j are extended through the holes in the channel and wings, and nuts 'i applied thereto serve to clamp the boxes to the channel in their working osition; the axle operatin to aline the boxes perfectly by reasons o the provisions for self-adjustment of the boxes. The bolts j extend-upward through the car bottom, to faeilitate the tightening of the bolts when they work loose by wear. The Chief purpose of the bolts y' is to hold the journal-boxes to the car if turned over or thrown off of thetrack, and they do not prevent the self-alinement of the boxes at all times.` v

The tops of the wings are made convex or arched transversely of the axle and bear directly upon the under side of the channelweb a, and either or both of the holes e and g is made With clearance around the bolts j so that the axle-box may rock upon the web of the channel, to aline the boxes with the axle when mounted upon the channel-bar.

The notches in the channel-flanges are made sufficiently wider than the wings d to permit the self-adjustment of the boxes 'in a horizontal plane, to compensate for any lack of alinement between the channed-bar and the working position of the axle.

lt will thus be seen that the clearance between the sides of the wings and the notches d permits adjustment in a horizontal plane,

while the clearance between the ends of the lugs f and the interior of the channel-fianges a' (see Fig. 4) permits lateral adjustment of the boxes upon the channel, and the arched tops of the wings permit the adjustment of the boxes in a vertical plane; while the securing of the boxes with all these compensations is provided by the bolts j, which clamp the boxes to the channel, and to the bottom of the car, if desired.

The clearance provided adjacent to the adjustable parts may be made of any magnitude to provide an adequate self-alinement for these parts.

Fig. 2 shows the rolls within the bore of The employment of the wings and lugs to transmit thrust, combined with the arched top, gives great strength to the box for the amount of metal employed, while the distance from the center of the axle from the car-bottom is reduced to the mini mum, which is a point of great importance.

The advantages of this Construction may be summed up as follows:

First, that it permits adjustment in a horizontal plane-- 4 i T I Second, that it permits lateral adjustment of the boxes upon the channel- Third, that the arched top to permits the adjustment of the vertical planea Fourth, that the clearance provided adjacent to the adjustable any magnitude desired.

The snug fitting of car axle-boxes bethe wings boxes n 'a tween the flan es of a channel-bar does not' aford the sel -adjustment of the boxes to 'adapted to fit said notches and held web next' the notches,

channel-bar with transverse part may be made of C the axle which is Secured by my Construction, and such snug fitting is not claimed herein, as the essential feature of my invention is the mountin of the boxes upon a channel-bar between t e flanges, and provding means upon the boxes to engage the flanges longitudinally and laterally with clearance for self-adjustment of the boxes between the flanges. The precise form of the parts is not therefore essential, but the channel-bar may be made of a casting instead of wrought-metal as shown, and the means of engaging the boxes with the fianges may be varied without departing from the invention if the clearance be provided to afl'ord the self-adjustment described.

Having thus set forth the nature of the invention what is claimed herein is:

1. The combination, with the floor of a mining or similar car, of a channel-bar secured transversely beneath the car-body with the fianges projected downwardly, and axle-boxes fitted between the fianges near the opposite ends of the channel, and provided with means to engage the fianges longitudinally and laterally thereof with clearance for self-adjustment of the boxes between the flanges. v

2. A car-axle mounting, comprising a channel-bar with transverse notches near its ends and axle-boxes having projections thereby against end-thrust.

3. A car-axle mounting, comprising a channel-bar with transverse notches in its fianges near their ends, and axle-boxes fitted between the flanges and having wings adapted to fit the said notches and arched upon the side next to the channel-bar to bear adjustably thereon.

4. A car-axle mounting, comprising a channel-bar with transverse notches in its flanges near their ends, and axle-boxes having wings fitted with clearance to the said notches and arched upon the side next to the channel-bar, whereby the box s permitted adjustment both horizontal and vertical planes.

5. A car-axle mounting, comprising a channel-bar with transverse notches 'in its fianges near' their ends, and bolt-holes in its and axle-boxes having wings fitted to the said notches, and bolts extended through the wings and channelweb and the floor of the car, thus connecting all the partsby the same bolts. i

A car-axle mounting, comprising a notches in its flanges near their ends and bolt-holes in its web next the notches, axle-boxes having wings fitted to the said notches and arched upon the side next to the channel-bar, and the ends of the wings being recessed upon the under side and provided with bolt-holes 1 correspondng to the bolt-holes in the chanfrom the boxes at opposite sides of the Wings t nel-Web, for the inserton of bolts to secure and fitted to the nner sicles of the fianges, 10
